Feeding auxiliary device of jaw crusher

Abstract

The invention relates to a feeding auxiliary device of a jaw crusher, wherein the feeding auxiliary device comprises a shell, a fixing plate is arranged in the shell, a straight rod is arranged on the right side of the fixing plate, the front end and the rear end of the straight rod are each sleeved with a cylinder rotating around the axis, four baffles are evenly distributed on the circumferential face of each cylinder, a groove is formed in the front end face of each baffle at the rear end, and a check block is arranged on the rear end face of each baffle at the front end; the check blocks and the grooves are in spacing fit, through holes are formed in the front side and the rear side of the lower end of the fixing plate, and levers are arranged in the through holes; a sliding block is arranged at the upper end of the fixing plate; transverse rods are arranged at the left end and the right end of the sliding block respectively; the rotating directions of the two transverse rods are opposite; a flat plate is arranged on the right side of the fixing plate, and the middle part of the flat plate is fixed on the transverse rod at the right end; a transverse plate is arranged on the left side of the fixing plate, and the middle of the transverse plate is fixed to the transverse rod at the left end; and vertical rods are respectively hinged to the front and rear ends of the transverse plate. By means of the displacement difference generated by unbalanced stress of baffles on the front side and the rear side, the flat plate rotates to change the discharging amount of the front side and the rear side, uniform discharging of the jaw crusher is achieved, the crushing efficiency is greatly improved, and the material returning phenomenon is reduced.

Description

technical field [0001] The invention relates to the field of coarse crushing, in particular to a feeding auxiliary device for a jaw crusher. Background technique [0002] When the jaw crusher is performing crushing operations, since the material itself is large and small in the coarse crushing stage, it will inevitably cause uneven feeding when it is transported by the conveyor belt, and the uneven feeding amount will affect its crushing efficiency. Too little material will greatly reduce its crushing efficiency, and too much material will cause return material, and even damage the jaw plate in severe cases, increasing the crushing cost; [0003] Since the conveyor belt and the receiving jaw plate of the jaw crusher have a certain width, when the material falls from the conveyor belt to the jaw plate, the material will also be unevenly distributed in the width direction of the jaw plate, resulting in the material falling on the jaw plate. The area is concentrated, and the p...
